Yesterday we reviewed the BitBox02 and named its single biggest weakness: no air-gap. Every transaction requires a USB cable to a computer.

Then we noted, somewhat awkwardly for our own review, that the Blockstream Jade Plus costs about the same and is air-gapped. Several readers asked the obvious follow-up. So here's the Jade Plus on its own terms.

The basics

The Jade Plus is made by Blockstream, the Bitcoin infrastructure company behind the Liquid sidechain, Core Lightning, and Blockstream Satellite. It launched in January 2025 as the flagship of a three-device lineup:

Jade Core — $99 — entry model, added April 2026
Jade Classic — $79 — the original device
Jade Plus — $149–$169 — flagship, air-gapped

Pricing per CryptoSlate and Hardware-Wallets.net. Note the Classic is cheaper than the Core despite being older — Blockstream's lineup naming is genuinely confusing, and you should check the current store listing rather than trusting any roundup's price table, including ours.

What makes it different: real air-gap

This is the headline feature and it deserves precision, because "air-gapped" gets used loosely.

The Jade Plus has a built-in camera and a battery. Together, those two components mean the device can sign a transaction while completely disconnected from any computer — you display a QR code on your screen, the Jade's camera reads it, you approve on-device, and the Jade displays a signed QR code back. No cable, ever.

Blockstream extended this to firmware updates, which is the part most air-gapped devices skip. On many "air-gapped" wallets you still have to plug in to update. The Jade Plus doesn't.

Why this matters: if your computer is compromised by malware, a cabled hardware wallet is still meaningfully protected — the private keys never leave the secure element. But the attack surface is real. Malware can swap the destination address you're sending to, and if you're not carefully verifying on the device screen, you sign away funds to an attacker. An air-gapped device with a decent display forces that verification step and eliminates the USB attack surface entirely.

For most people, this is over-engineering. If you're holding a meaningful stack, it isn't.

The display

The Jade Plus has a 66% larger IPS display than the Classic. This sounds like a spec-sheet detail and isn't.

The entire security model of a hardware wallet rests on you actually reading the destination address on the device screen and confirming it matches what you intended. On a cramped monochrome OLED, people skim. On a larger color display, they read. Blockstream making the screen bigger is a security improvement dressed up as a usability one.

Build and materials

Precision-machined aluminum alloy housing. The Classic is plastic. The Plus feels — and is — built for a device you'll own for years and occasionally drop.

The battery is worth flagging as a mixed blessing. It enables air-gapped operation, which is the whole point. It's also a consumable component that degrades. Lithium cells lose capacity over years, and if the battery eventually fails on a device with no USB signing fallback, you'll want to be certain your seed backup is sound. It will be — the seed is what matters, not the device — but plan for the device being replaceable and the backup being permanent.

Bitcoin and Liquid only

The Jade Plus supports Bitcoin and Liquid assets. No Ethereum, no Monero, no altcoins of any kind.

If you hold anything besides Bitcoin, this is a hard stop and you should look at a Ledger or a multi-coin BitBox02 instead. If you're Bitcoin-only, it's a feature: less code, fewer chains, fewer places for a bug to hide. It's the same reasoning behind Coldcard's and BitBox's Bitcoin-only builds.

Liquid support is a genuine differentiator for a narrow group. Liquid is Blockstream's own sidechain, used for faster settlement and confidential transactions — mostly relevant to traders and issuers. Most readers will never touch it.

Open source, and what that's worth

The Jade firmware is fully open source and published on GitHub. Anyone can read it, and security researchers do.

Set against the field:

Ledger uses a proprietary secure element with closed-source firmware components. You get certified tamper resistance and a "trust us" layer you cannot audit.
Trezor's Model One historically shipped with no secure element, relying on open code plus a passphrase.
BitBox02 pairs an ATECC608A secure element with fully open, reproducibly buildable firmware.
Jade Plus is fully open source with a security architecture built around its own chipset.

We covered the Ledger-vs-Trezor tradeoff in our June comparison and the BitBox02's version of it yesterday. The short version: closed secure elements buy you certified hardware resistance at the cost of auditability. Open designs buy you verifiability. Reasonable people land in different places, and anyone who tells you the answer is obvious is selling something.

Where it falls short

Blockstream is not a neutral party. The company has commercial interests in Liquid and in Bitcoin infrastructure broadly. That isn't disqualifying — every wallet maker has commercial interests — but Liquid support being a headline feature of a wallet built by the company that runs Liquid is worth noticing.

Air-gapped workflows are slower. Scanning QR codes back and forth takes longer than plugging in a cable. If you transact frequently, you will feel it. This is the tradeoff, not a defect, but people underestimate how much friction they'll tolerate.

Confusing product lineup. Three devices, overlapping prices, and a Classic that costs less than the Core. Buyers get this wrong.

No breach history — so far. Blockstream Jade has no known security incidents. After the Coldcard firmware flaw that cost one holder 594 BTC — which we covered on August 2 — a clean record is worth noting. We'll state it the same way we did for BitBox: no incidents so far is not a guarantee, and any manufacturer's record can change with one firmware release.

Jade Plus vs. BitBox02 vs. Ledger

The honest comparison, at roughly comparable price points:

Price — Jade Plus: $149–$169 | BitBox02 (BTC-only): $150 | Ledger Flex: higher tier
Air-gapped — Jade Plus: yes (QR + camera) | BitBox02: no | Ledger Flex: no
Open source — Jade Plus: fully | BitBox02: fully | Ledger Flex: partially
Secure element — Jade Plus: yes | BitBox02: yes (ATECC608A) | Ledger Flex: yes (proprietary)
Coins — Jade Plus: BTC + Liquid | BitBox02: BTC only (or multi) | Ledger Flex: multi-coin
Mobile / Bluetooth — Jade Plus: no | BitBox02: no | Ledger: yes (Nano X)
Display — Jade Plus: large IPS | BitBox02: 1.1" OLED | Ledger Flex: touchscreen

Buy the Jade Plus if you're Bitcoin-only, want air-gapped signing, and value open-source verifiability over brand support infrastructure.

Buy the BitBox02 if you want a Swiss-made device with a proven secure element, don't need air-gap, and prefer a simpler USB workflow.

Buy a Ledger if you hold multiple assets, want mobile signing, or want the largest support organization behind your device. It's the pragmatic pick for most people, and you can buy direct from Ledger's store.

Buying advice

Buy direct from the manufacturer. This is not optional. Hardware wallets bought from Amazon marketplace sellers, eBay, or any third party carry supply-chain tampering risk — a device pre-loaded with an attacker's seed looks identical to a legitimate one. Blockstream's own store is the only source we'd use.

Verify the packaging. Check tamper-evident seals on arrival. If anything looks off, don't initialize it.

Generate your own seed. A hardware wallet should generate its seed on-device, in front of you, on first setup. If a device arrives with a seed phrase already printed on a card, it is a scam. Every time, without exception.

Prices move. Confirm the current Jade Plus price on Blockstream's own store before buying — the roundups we sourced list a $20 spread, which usually means someone's data is stale.
